I agree with using technology but the Mata offside- as you say effectively his knee cap was to mind my ridiculous. I always thought the benefit of any doubt should go to the forward. And even as a Huddersfield fan I wouldn't have been massively aggreived.

The principal of the knee makes sense as the argument was that it could be used to play the ball and score a goal and therefore was officially offside... situation in general is that (as I understand) the VAR is only to be used for 'clear and obvious' mistakes which this didn't seem to be given the debatable decision made to chalk the goal off...

Fundamentally the decision can't take away (right or wrong) from players basically lining up to take a kick off to then be told 4 or 5 minutes later that the goal isn't a goal
